Glad you're on the mend
@Deco33 wish I'd posted that photo earlier when I first read about it.
Most likely a nasty contaminated pill tbh but there comes a point (for some of us) where stopping is just the next logical step because nobody needs the sort of cr@p in their lives that experience brought you. I had a horrid experience flip me over the edge of deciding chems were getting the heave-ho lock, stock and 2 smoking barrels and I've never looked back and questioned whether I was right to conclude that.
What's hard is deciding that the overall costs/onging risks outweigh the overall benefits when something's become normalized / borderline habitual and cutting it out rather than cutting it down ! A small handful of dabbles in the years that followed were enough to remind me why I went down that route, the conclusion was always the same - just wasn't worth it (time, risk, money, inconvenience, long term health toll etc etc).
Often a wake-up call comes when and in a way you least expect. It's equally easy to rationalize everything away if you want to. We're all different. Hope you make whatever choice your gut tells you is right for you.
I'm naturally depressive and have a very addictive personality, prone to excess. It took me well over 30 years and a couple of hard knocks to accept drink and drugs don't sit as well with me as some other people and life without either can actually be good too. I also learned hard that I love my car and the freedom it brings far more than I love a drink, a bump or a toke. I'm 100% behind people who make responsible decisions of their own either when they have a lot to lose or they simply have personal factors which mean their cost-benefit analysis is different to the guy they're standing next to, who maybe doesn't.
